Introducing the newest Maglite XL200 LED Flashlight. The Maglite XL200 is the latest member of Maglite’s tactical-sized XL Series of flashlights. The XL200 operates on three common AAA batteries (Included) for 172 lumens of maximum output, rivaling rechargeable and lithium CR123 powered flashlights, and has a new user interface that combines the XL50’s ease-of-use with the features of the XL200.SpecificationsBrightness: 172 to 14 lumensRuntime: 2h 30m to 218h Battery: 3 x AAALength: 4.8"Diameter: 1"Weight with Batteries: 3.68 oz5 Modes High PowerStrobeNite LiteSignalSOS1 Click: NormalWith the light turned off, press and hold the switch. Rotating the light left and right will adjust the brightness. Once the desired brightness is achieved, releasing the switch will set the brightness. The light will remember the setting after switching off, and the memory function is non-volatile (which means the setting won’t be lost when the batteries are removed). The stored brightness setting applies to all modes.2 Clicks: StrobeThe strobe feature is designed for disorienting or getting somebody’s attention. To adjust the strobe speed, hold the button on the second click and rotate the light left or right. The strobe speed can go as low as a slow flash of about once every two seconds. Click the button to disengage.3 Clicks: Nite LiteThis is one of the most interesting modes of this light. When the light is set down, it will dim to a faint glow until the light is moved. Unlike the XL100, Nite Lite mode returns to the stored brightness level unless it is below ~50%, in which case it will return to 50%.4 Clicks: SignalSince the XL200 uses an electronic switch, there is no momentary on. Instead, twisting the light to the left or right will turn it on. Rotate the light back to the original position to turn off. Click the button again to turn the light off.5 Clicks: SOSSOS is the International Morse Code Distress Signal, which is three short flashes, three long flashes, and three short flashes. Press the button again to disengage.
